Chung-En Lee updated HDDS-16662:
--------------------------------
Fix Version/s: (was: 2.2.2)
> Refactor shared HMAC-SHA256 logic in S3 signature validators
> ------------------------------------------------------------
>
> Key: HDDS-16662
> URL: https://issues.apache.org/jira/browse/HDDS-16662
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: S3
> Reporter: Huang Kuan Hao
> Assignee: Huang Kuan Hao
> Priority: Minor
> Labels: pull-request-available
> Fix For: 2.3.0
>
>
> {{ChunksValidator}} and {{AWSV4AuthValidator}} each maintain a thread-local
> {{Mac}} and implement HMAC-SHA256 initialization and signing. Share this
> logic through {{ozone-common}} so request, chunk, and trailer verification
> use the same primitive.
> Keep signing-key derivation in OM and the previous-signature chain in
> {{ChunksValidator}}. Preserve signature parsing, constant-time comparison in
> {{ChunksValidator}}, and existing error responses.
> Verify request authentication, consecutive signed chunks, signed trailers,
> invalid signatures, and independent requests using different keys. The
> refactor should preserve behavior and avoid sharing mutable request state.
> Follow-up to HDDS-15142: https://github.com/apache/ozone/pull/11222
